My present invention relates to supporting means for a substantially cylindrical, hermetically-sealed compressing unit such as is more fully described and claimed in the co-pending applications of Charles R. Neeson, Serial No. 145,585 to 145,589, inclusive, filed May 29, 1937, and Serial No. 180,099, filed December 16, 1937, all of which applications'are assigned to applicants assignee, and of which Serial No. 145,589

is now Patent No. 2,137,965, issued November 22,

' 1938, and Serial No,- 180,099 is now Patent No.

The present invention has to do particularly with an improvement in the mounting of a comi3 pressor to as to permit the compressor to vibrate,

oscillate or partially rotate in all directions, while limiting such movements to a substantial degree. It was found in connection with the compressor mounting illustrated and described in the fore- 2o going applications that-the operation thereof was completely satisfactory except in circumstances beyond the control of the manufacturer. such, for example, as overzealous demonstration of the mounting of the unit" by salesmen and exhibitors.

The unit, being mounted on a single resilient suspension member, was capable of swinging far beyond the degree necessary for dampening of noises and vibrations occasioned by the operation of the compressor, and it was found that demonstrators sometimes pushed or kicked the unit beyond the point to which connecting pipes could be moved, with the result that the compressing unit lost its charge of refrigerant through a broken pipe or other connecting means. The 3:; object, of the present invention is to provide a mounting having all of the advantages of the mounting described in the aforementioned applications and having limiting means to prevent the acidental breaking of connecting refrigerant 40 P p s.

The present mounting comprises a suspension member consisting of a bolt fastened to the top of the compressing unit and having its head supported by a block of resilient material which is 5 carried by a mounting plate supported within an air conditioning or refrigerant condensing unit, supplemented by movement limiting members extending from the lower end of the compressing unit to a suitable support, these limiting members each comprising a resilient intermediate section.

The objects and advantages of the present invention will be more clearly apparent from inspeotion of the following specification taken in connection with the accompanying drawing 55 wherein like numerals refer to like parts throughout. In the drawing, Fig. 1 is a front elevation of part of an air conditioning or refrigerant condensing unit showing a compressing unit mounted therein; Fig. 2 is a plan view of the apparatus shown in Fig. 1; and Fig. 3 is a detail view on an 5 enlarged scale, partly in cross-section, of a movement limiting means comprising a portion of the present invention.

The compressor 20 is shown as being mounted in a cabinet or frame 2|, the frame comprising 10 channel members 22 and 23 upon which is supported a mounting plate 24. The mounting plate 24 is provided with an opening through which passes a bolt 30 having one end fastened into the top of the compressing unit 20 and having its 16 head supported by a resilient block 3| which 'is supported by a collar 32 bolted to the mounting plate 24. The bolt 30 is substantially in line with the center of gravity of the compressing unit so as to permit the same to hang vertically, the g0 resilient block 3| permitting free movement of the compressing unit.

In order to prevent undue swinging of the compressing unit 20 to such an extent as would cause the breaking of connecting pipes, such as pipe 25 40, in spite of flexible inserts (not shown) therein, means are provided to limit the movement of the compressing unit, such means comprising an arm or arms 4| extending from the lower end of the compressing unit 20. The arm is threaded at so 42 to permit the same to be screwed into a threaded opening in the wall of the compressing unit and a locking nut 43 is provided to hold the arm in proper position. The opposite end of the arm is suitably fastened to a plate 44 to which is bonded or otherwise secured a resilient member 45, the opposite surface of which is bonded or otherwise secured to a plate 43 similar to plate 44. The member 45 therefore is capable of compression or extension so as to permit plates 44 and 46 to approach or recede from each other, and alsomay be distorted in shear so as "to permit plates 44 and 43 to move out of line with each other in any direction. The plate 46 is suitably A fastened to the frame 2| as by means of a bolt 41. Other resilient means could be substituted for the rubber member but the same is preferable since noises are dampened or prevented from passing through arms 4| to the framework 2|, which, therefore, permits the single member to perform both functions of limiting while permitting movement of the compressing unit in all directions, and of preventing the substantial passage of noises and vibrations from the compressing unit to the frame and'surrounding walls or floors.

Having described the preferred embodiment of my invention, it should be apparent to those 5 skilled in the art that modifications in arrangement and details thereof may be achieved, and

- 1. A mounting for a hermetically-sealed compressing unit comprising a resilient member carried by said unit substantially in line with the center of'gravity thereof, a frame to which said 5 resilient member is fastened to support the weight of said compressing unit, and movement limiting means extending laterally from the lower end of said compressing unit, said means comprising an arm extending from said compressing unit and a go rubber member bonded to the free end of said am and to said frame.

2. .A mounting for a hermetically-sealed compressing unit comprising a resilient member carried by said unit substantially in line with the as center of gravity thereof, a frame to which said resilient member is fastened to support the weight of said compressing unit, and movement liniiting means extending laterally from the lower end of said compressing unit, said means comprising an an arm extending from said compressing unit, a rigid member carried by said arm, a second rigid member mounted on said frame, and a rubber block having opposed faces bonded to saidrigid members. a

3.- A mounting for a hermetically-sealed compressing unit comprising a resilient member carried by said-unit substantially in line with the 6 center of gravity thereof, a frame to which said resilient member is fastened to support the weight of said compressing unit and' movement limiting means extending laterally from the lower end of said compressing unit, said means comprising a 10 plurality of arms extending from said unit, a rigid member carried by each of said arms, and a plurality of rubber blocks each having a face bonded to one of said rigid members and another face bonded to a part of said frame. l5

4. A mounting for a hermetically sealed compressing unit comprising a resilient member carried by said unit substantially in line with the center of gravity thereof, a frame to which said resilient member is fastened to support the weight of said compressing unit, and movement-limiting means extending laterally from the lower end of said compressing unit, said means comprising a plurality of arms extending from said unit, a rigid member carried by each of said arms, other rigid members mounted on said frame, and a plurality of rubber blocks each having a face bonded to one of said rigid members carried by said arms and another face bonded to one of said other rigid members mounted on said frame.
